1.对于接口自动化测试,一般接口以json形式发送返回,往往我们就需要遍历json文件中所有key,value以及修改替换key对于的value。
例如json发送/接收的文件:
SendRegisterVerificationCodejson_txt = """
{
"header":{
"funcNo": "IF010002",
"opStation": "11.11.1.1",
"appId": "aaaaaa",
"deviceId": "kk",
"ver":"wx-1.0",
"channel": "4"
},
"payload": {
"mobileTel": "13817120001"
}
}
"""
需要查找所有的报文中的key,value,这个json是字典包含字典的形式,如遍历字典后,依旧含有 key对应的value值是字典,需要继续遍历,此时需要用递归进行处理
代码如下:
1 import json 2 #json文件发送形式 3 SendRegisterVerificationCodejson_txt = """ 4 { 5 "header":{ 6 "funcNo": "IF010002", 7 "opStation": "11.11.1.1", 8 "appId": "aaaaaa", 9 "deviceId": "kk", 10 "ver":"wx-1.0", 11 "channel": "4" 12 }, 13 "payload": { 14 "mobileTel": "13817120001" 15 } 16 } 17 """ 18 date_json = json.loads(SendRegisterVerificationCodejson_txt) 19 print(date_json) 20 print("*"*10) 21 # 发送时,每次需要注册新的手机号码,就需要json每次提示mobileTel的value进行发送 22 #遍历json文件所有的key对应的value 23 dic ={} 24 def json_txt(dic_json): 25 if isinstance(dic_json,dict): #判断是否是字典类型isinstance 返回True false 26 for key in dic_json: 27 if isinstance(dic_json[key],dict):#如果dic_json[key]依旧是字典类型 28 print("****key--:%s value--: %s"%(key,dic_json[key])) 29 json_txt(dic_json[key]) 30 dic[key] = dic_json[key] 31 else: 32 print("****key--:%s value--: %s"%(key,dic_json[key])) 33 dic[key] = dic_json[key] 34 35 json_txt(date_json) 36 print("dic ---: "+str(dic))
输出结果:
data_json: {\'header\': {\'funcNo\': \'IF010002\', \'opStation\': \'11.11.1.1\', \'appId\': \'aaaaaa\', \'deviceId\': \'kk\', \'ver\': \'wx-1.0\', \'channel\': \'4\'}, \'payload\': {\'mobileTel\': \'13817120001\'}}

2.对于接口测试,json主体内容不变,一般我们都是修改json内key对于的value值进行测试,这个接口是手机号注册的接口,正常情况我们都是修改手机号进行测试;
如将key --\'mobileTel\'对于的value-- \'13817120001\'修改,假如修改为13333333333;
那我们需要在遍历json字典key值后,比对如果遍历到对于的key则修改其value。
def check_json_value(dic_json,k,v):
if isinstance(dic_json,dict):
for key in dic_json:
if key == k:
dic_json[key] = v
elif isinstance(dic_json[key],dict):
check_json_value(dic_json[key],k,v)
print("date_json 变更前 :")
print(date_json)
check_json_value(date_json,\'mobileTel\',\'13333333333\')
print("date_json 变更后 :")
print(date_json)
